Chelsea opened the defense of its UEFA Champions League title with a 2-2 tie with Italian champion Juventus after squandering an early two-goal lead on a pair of goals by Brazilian youngster Oscar, the second described as a "wonder goal" by Chelsea manager Roberto Di Matteo.

"It was a great [full]
debut," Di Matteo said. "He's a big talent. He has a bit of everything, he's still young and we're very lucky to have him in the team. He did a good job tactically, he scored two goals and the second
of them was a wonder goal. We shouldn't forget that he is still a young man -- he is only 21 -- but he is already quite established in his national team already."

Di Matteo also praised
the 21-year-old midfielder for his work marking Juve star Andrea Pirlo, but Oscar had to leave the game midway through the second half with an ankle injury. Di
Matteo said the challenge by Leonardo Bonucci was "a bad tackle" and ripped referee Pedro Proenca for not doing enough
to protect his players.

"If UEFA have a look," said Di Matteo, "that's good, but we have to move on from it."
